Geronimo Stilton (also known as The New Adventures of Geronimo Stilton in season 3) is an animated children's television series based on the book series of the same name by Elisabetta Dami. The series was produced by Italian studios Atlantyca Entertainment and Rai Fiction in collaboration with the French studio Moonscoop LLC for seasons 1–2, while for season 3 it was co-produced by Superprod, Back UP Media, and CNC, replacing the crew of Moonscoop.

The show ran for 78 episodes across three seasons, and it debuted on Rai 2 in Italy on September 15, 2009. The second season aired on October 24, 2011, and the third season on October 8, 2016, which the show ended on as of February 28, 2017. There are many differences from the book series, where as most of the main characters have new or swapped personalities (such as Geronimo being a lot more braver than he was in the books) and some of the characters from the book series, such as Petunia Pretty Paws, Hercule Poirat, The Thea Sisters, Creepella Von Cacklefur and Samuel S. Stingysnout, are never mentioned nor do they appear in any of the episodes in the TV series.


Geronimo Stilton is about the titular character, a mouse journalist and head of the Geronimo Stilton Media Group. He searches New Mouse City and places around the world for new scoops while having adventures along the way with his nephew Benjamin, cousin Trap, sister Thea and Benjamin's friend Pandora Woz. Most episodes share no story connections and are generally self-contained, though some episodes feature ties and characters from others.

She flies the team in her all-terrain Metamouse, which can turn into a submarine, boat, airship, rocket ship/moon rover and SUV truck to locations that Thea, Trap, Benjamin, and Geronimo are exploring for an articles in The Rodent's Gazette.
